Abstract: The systems, apparatuses and methods may provide a way to adaptively process and aggressively cull geometry data. Systems, apparatuses and methods may provide for processing, by a positional only shading pipeline (POSH), geometry data including surface triangles for a digital representation of a scene. More particularly, systems, apparatuses and methods may provide a way to identify surface triangles in one or more exclusion zones and non-exclusion zones, and cull surface triangles surface triangles in one or more exclusion zones.

Abstract: Systems, apparatuses and methods may provide for technology that partitions a three-dimensional (3D) scene into a plurality of layers including at least a foreground layer and a background layer. Additionally, the foreground layer may be rendered at a first rate and the background layer may be rendered at a second frame rate, wherein the first frame rate is greater than the second frame rate.
